Before O, the ultrasound showed 2 maturing follicles, at 16mm and 20mm. I hadn't yet had an LH surge, so I suppose they could have kept growing from there.
I went back 4 days later, which should have been after O (and in fact all the blood work indicated that was the case) - but I still had a 16mm. They are calling the ultrasound "inconclusive".
Was just curious if anyone ever experienced something similar?
